SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 245,554, dated August 9, 1881.

Application filed January 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES PEITIBONE, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification.

My invention relates to a separable button adapted to be used most particularly for buttoning coats or other heavymaterial, the novel features of which are set forth and described in the following specification and drawings making a part of the same.

In the accompanying drawings, Figure 1 is a plan view of my invention with the cover of the button removed. Fig. 2 shows the same view, but with thestem of the button unlocked. Fig. 3 is a vertical elevation on the line at w, Figs. 1 and 2, but showing the cover of the button therein, which is out through the center and in sections. Fig. 4 is a central section on line y y, Fig. 1, at right angles to the vertical plane of Fig. 3. Fig. 5 is a perspective view of the locking slide.

A represents the outer head or face of the button.

A represents the base-plate ot' the front or top of the button, attached to the cover A in the usual manner.

B represents the detachable stein.

B representsa plate forming theinside head of the button.

(t represents a hub rigidly attached to the plate A, and is provided with a female screwthread. The stem B is provided with a male screw-thread for engaging the female screwthread in the hub a.

O represents a sliding frame, which surrounds the hub a, and is provided at one end with a locking-pin, c.

D represents a post which projects up through the plate A. The upper end, 0, of the post D projects through and above the top of the slide O.

6 represents apivot or post in the baseplate A.

E represents a wire spring, which is securely fastened at one end to the post 0, and is bent to curve around the hub a and thence forward past the post or stud c. The pin a in slide 0, when the devices are in the position shown in Fig. 4, enters a hole, 0, pierced through the hub to and into the stern B, which prevents the stem B and plate B from being unscrewed and removed from the cap A A.

\Vhen it is desired to remove the stem of the button from the cap the stud D is pressed in toward the stem B, when pin 0 of the slide 0 is carried out of the hole 6 and the stem B can be unscrewed and removed. The tension of the spring E holds the pin cin its advanced position in the hub a.

In order to allow the stem B to be inserted without withdrawing the pin 0, the point of the stem B is made conical, so that it will push the pin 0 back as it is screwed in until the hole 6 in the stem B arrives at the point opposite the pin 0, when the spring E shoots the pin 0 into the hole 6 in the stem of the button and looks it in position.

This invention accomplishes a very important result not hitherto accomplished in re movable buttons, as the strain on the cap of the button is resisted by the screw in the rigid hub to engaging with the stem B, while the spring is not subjected either to the vertical or lateral strains imparted to the hub a, stem B, and locking-pin c.

It is obvious that other modes of operating the locking-pin 0 can be employed and different forms of springs can be combined with the slide to hold the pin 0 in position and to detach the same; but the plan herein shown I deem the simplest and best.

Having described my invention, what I claim as new is A detachable button composed substantially of the cap A A, screw-hub'a, stemB B, and an adjustable slide provided with a lockingpin, 0, substantially as herein set forth.

In testimony. whereof I have hereunto set my hand in the presence of two subscribing witnesses.
